Added PARALLELISM in load/dump of tables using new class QueryThread (extends Thread)
Modified methods loadData, dumpData and loadSplitData to dump/load parallely in cases that is useful by using the QueryThread class.
New method initializeDirs(String[]) to do some of the dir initialization that was in dumpData
Got rid of one of the getConnectionToNode method, not needed anymore
New important 2 final static variables: NUM_CONCURRENT_READ_QUERIES and NUM_CONCURRENT_WRITE_QUERIES. They define how much concurrency we want in reads/writes to nfs for loads/dumps

Creation of tools version 0.1:
Freezing tools rev81 to tag tools-0.1
I am planning to change completely some of the classes: DataDistribution and ClusterConnection. Will continue developing on trunk while we have this freeze so others can use programs as they are now.
